Sorry for the delay in replying.
The recent numbers for GM suggest this is a new horse; specifically, her bad races were efforts in the past. My expectation is that she will break through her recent top, and soon.
For this race, I thought a 12/13 would do it. The two horses that have run 10 or better in the past seemed unlikely: Stage Down (the winner)because she\'s a shipper with a spacey line; and Nice Fish, for mostly obvious reasons.
With hindsight, the knock against the bet is that it\'s too soon. At this level, horses need more time (8-12 weeks) to recover.
BO/BI\'s are tricky. Without GM\'s last race, the BO would be off-putting, but just that wouldn\'t discourage me from betting the horse. In some cases (classy 2/3 year olds running new tops), a BO seems to be a positive sign.
Hope this helps, thanks for your posts.
